Probably the most annoying form of scratch damage is caused by sandpaper. When decorators use sandpaper or sanding blocks to remove paint and prepare wooden frames for painting, some do not think about the glass.
To make the handling of the paper easier, the tendency is to curve the paper over your fingers to allow better access into the corner between the wood and the glass. Unfortunately, this also brings the paper in contact with the glass and scratches it.
If you try to remove scratches this close to the edge of the glass, you will almost certainly cause distortion and hazing as you have no room to blend the glass back into itself. The only remedy to this is to remove the glass from the frame before you repair it. In most cases, this makes the cost of repair non-cost effective and replacement is usually the cheaper option.
Repair Solutions: for large areas or multiple units
If you have a large area or multiple units to repair, our advice would be to call a professional glass polisher. As they say, time is money and this includes your time.
It would be misleading to try and give a general cost of repair on a website as each scratched glass situation is different, but for large areas of scratched glass or for multiple units, services of a qualified glass polisher offer genuine savings, often in excess of 80%, on the cost of replacing scratched windows and doors.
For areas greater than 50 sheets of A4 we would recommend you ask for a senior technician to visit your site to assess the works required and provide a written quote.
The Cost Effective Option. On paper, professional glass polishers are not the cheapest glass polishers on the market, but the reality is that a Guild qualified glass polisher will repair a least twice the area than that advertised by most others othering scratched glass repair services. This makes our members extremely cost effective and our members are still the only glass polishers able to guarantee distortion free repairs.
Repair Solutions: for small areas or single units
For smaller areas or for single unit repairs, employing a professional glass polisher may not be the most cost effective option. You might find that a D.I.Y Scratched Glass Repair Kit would be a more cost effective option for you.
A quick note about D.I.Y Kits. There are a number of kits on the internet that claim to remove scratches from glass. Please be careful. Kits with just a felt pad and polishing compound will not remove anything other than very, very fine hairline scratches. The same can be said for kits containing 'Jewlers Rouge', polishing powder, usually pink, which you mix with water.
